Using external struct as command parameters and result

[MarcWadai]

When using a struct that was not defined on my tauri app but on an external crates as a parameter for my procedure. I got this error !

the trait bound Toto: Type is not satisfied

I guess it is because the external crate doesn't implement specta Type trait.

How can i make the external struct implement the trait Type ?
I saw some solutions where we can redefine a struct and use it as a type for an attribute in our wrapper specta-rs/specta#284.
But in my case I don't want to define an attribute, but use directly the struct as is. Like below. Is it possible ?

use another_crate::Profile

#[taurpc::ipc_type]
struct MyProfile(Profile);

An exemple of implementation that I did which still does not work :

use another_crate::DatabaseStats

#[taurpc::ipc_type]
struct MyDatabaseStats() {
    #[specta(type = TDatabaseStats)]
    database_stats: DatabaseStats
}

#[taurpc::ipc_type]
pub struct TDatabaseStats {
    pub size: u64,
    pub event_count: u64,
    pub room_count: u64,
}

Even by mirroring the struct definition on my file, I got and error since the origin DatabaseStats only implement Serialize and Deserialize (doesnt implement Clone)

So I try to just do

#[taurpc::ipc_type]
struct MyDatabaseStats(TDatabaseStats);

#[taurpc::ipc_type]
pub struct TDatabaseStats {
    pub size: u64,
    pub event_count: u64,
    pub room_count: u64,
}

Which doesnt generates errors, but will need to have type conversion when using in my resolvers since the method I am using is waiting for a DatabaseStats and not TDatabaseStats.
Moreover I have to mmultiply this for every struct and enum I am using.

Is there a better way ?

Those are the main two solutions to these sort of problems. If the crate is big enough we can also add support for it directly into specta.

Can you share more about the error your getting with the #[specta(type = ...)] approach?

I suspect that would be the best solution and I would expect it to work work given the limited context you've shared, other than the struct MyDatabaseStats() having the () but I assume that's just a typo.
